The Estimation of the Gravity Value in Qomolangma Peak

It is meaninful to estimate the gravity value in Qomolangma peak.When the wave length for the topographic load λ ≤50 km,the crustal strength is strong enough to keep the crust not deformed.Therefore,it is improper to use Airy_Heiskanen or Pratt_Hayford local compensation model to estimate the gravity.On the basis of this idea,utilizing four kinds of formulas,we give the gravity of everest (976 970±7)×10 -5 m·s -2 .
